TPA701D Description

Short technical summary and product information.

The TPA701D from Texas Instruments is a mono, Class-AB audio power amplifier optimized for low-voltage applications requiring internal speakers. It accepts analog input and is suitable for voice band frequencies, though characterized up to 20 kHz.

This amplifier delivers up to 700mW of output power into an 8Ω load when operating at 5V, and 250mW at 3.3V, utilizing a bridge-tied load (BTL) configuration. The BTL setup minimizes the need for external output coupling capacitors, which is advantageous for battery-powered devices. It operates with a wide power supply compatibility from 2.5V to 5.5V.

Key electrical characteristics include a typical quiescent current of 1.5 nA in shutdown mode, making it power-sensitive. The device offers thermal and short-circuit protection. It is available in compact surface-mount packages, including SOIC and the space-saving HVSSOP PowerPAD.

The TPA701D is well-suited for applications such as mobile phones, tablets, wearables, and other portable electronic devices where efficient audio amplification in a small form factor is required.
